MC1K Handheld Radiation Alert® Detector

The MC1K is a handheld survey meter using a built-in energy compensated GM detector. It detects gamma and x-rays up to 1000 mR/hr over 4 selectable ranges. A beep sounds and a count light flashes with each event detected.

Detector: Energy compensated halogen-quenched GM tube.

MC1K Energy Sensitivity: Detects gamma and x-rays down to 40 keV. Response is flat from 40 keV up. Normal background, approximately 4 CPM.

Audio Indicator: Internally mounted beeper (can be turned off for silent operation).
